![**Calculating Reaction Free Energy (ΔG)**
In this example, we will calculate the reaction free energy (ΔG) for a chemical reaction under given conditions.
### Initial Setup:
A chemist prepares a reaction vessel containing the following components:
- 0.911 g of calcium phosphate (\( \text{Ca}_3(\text{PO}_4)_2 \)) solid
- 0.697 M calcium (\( \text{Ca}^{2+} \)) aqueous solution
- 0.958 M phosphate (\( \text{PO}_4^{3-} \)) aqueous solution
The reaction is carried out at a temperature of 25.0 °C.
### Chemical Reaction:
The chemical reaction to consider is:
\[ \text{Ca}_3(\text{PO}_4)_2 (\text{s}) \leftrightharpoons 3\text{Ca}^{2+} (\text{aq}) + 2\text{PO}_4^{3-} (\text{aq}) \]
### Objective:
Calculate the reaction free energy (ΔG) for this reaction using the thermodynamic information available in the ALEKS Data tab. Be sure to round your answer to the nearest kilojoule (kJ).
### Input Field:
The final answer should be entered into the provided input field, expressed in kilojoules (kJ).
\[ \boxed{\hspace{30px}\text{ kJ}\hspace{30px}} \]
